| | Quantitative Risk Assessment & Hazard and Operability Study
In short, QRA is a technique to evaluate risk associated with a particular “Hazardous Activity” that potentially have great impact on human, financial and its surrounding environment.
Quantitative Risk Assessment Quantified Risk Assessment (QRA) is a technique measuring and ranking the various contributory risks associated with the operation of facilities, in particular those risks with the potential to cause fatalities. It is a follow-up from techniques such as HAZID and HAZOP, which identify the hazards associated with a facility and enables quantification of the consequences, escalation potential and risk.
Hazard and Operability Study HAZOP (Hazard and Operability Study) is a formalised process for identifying and examining potential deviations from design intent/normal operations that could result in a hazardous unsafe situation or operability problem. The essence of the HAZOP Analysis approach is to review process drawings and/or procedures in a series of meetings, during which a multi-disciplinary team uses a prescribed protocol (a combination of deviation guide words and process parameters) to methodically. |
